VALVE.

SPECIFICATION forming part of Letters Patent No. 333,941, dated January5, 1886.

Application filed April 27, 1885. Serial No. 163,514.

To all whom it may con/cern,.-

Be it known that I, HENRY R. FRIsBIE, a citizen of the United States,residing at Cromwell, in the county of Middlesex and State ofConnecticut, have invented new and useful vImprovements in Valves andStop-Cocks, of

which the following is a specification.

This invention relates to improvements in valves and stop-cocks, andpertains more particularly to that description of said articlesdesignated as globe-valves, the object being to provide improved devicesattached to the diaphragm ofthe valve, and having a fixed relation tothe moving valve proper, whereby the latter, when connected to thespindle of the valve by a special device, as hereinafter described, isprevented from moving laterally off from the spindle, and is properlyguided in its motion, and also to provide an improved removable seat forthe aforesaid class of valves.

In the drawings forming part of this speciiieation, Figure l is alongitudinal section of a globe-valve embodying my improvements. Fig. 2is a perspective view of the removable seat of the valve, having thereonthe valveguides b b b; and Fig. 3 is a like view of the valve proper.

In the drawings, A is the body of the globevalve, having therein theusual diaphragm, a, provided with the customary valve-openingtherethrough, which opening is screwthreaded, as shown, and into thesame is screwed the removable seat-ring D, said ring consisting of thescrewed portion 1, which is adapted to screw into said diaphragm, theprojecting collar z, having a bearing on the diaphragm thereunder, andthe upwardlyprojecting seat for the valve, (lettered o2) said ring beingalso provided with the upstanding valve-guides b b b, which are fixedthereto on collar z, a little removed from the side of the seat c. Inputting the seat-ring D into the diaphragm na washer of rubber or othersuitable material may be placed under the collar z should it be neededfor preventing leakage through the screwed parts. Ordinarily,however,(the common lead packing or cement will be sufficient to makethat `joint tight. The

seat o on ring D is adapted to receive the fiatfaced valve e having anysuitable rubber or other packing, o, attached thereto, although (Nomodel.)

the common beveled valve-seat may be formed on ring D, if preferred, orany other suitable one. The said removable valve-seat is easily removedfrom the diaphragm for replacing a worn-out one by a new one, wherebythe cost of a new body, A, is obviated, and for retinishing the face ofthe ring o' when it has become imperfect and causes leakage. The spindlec operates in the hub d in the usual manner, and has a collar, o, aroundits lower end.

The valve proper, e, has formed on its upper side a socket to receivethe lowerend of the spindle c and its collar o, consisting of a wall, 5,standing up at right angles to the face of the valve, the main portionof said wall being concentric with the border of the valve, but havingan opening at one side, l

as shown. A groove, 6, is formed in the inner face of said wall, wherebyprovision is made for the reception in said socket of the collared endofthe spindle c, as shown, whereby the latter and the valve are soconnected that the spindle swivels or turns freely in the latter, andthe valve is compelled to obey the movements lengthwise of the spindle,but no connection exists between the valve and the spindle to preventthe former from moving laterally off from the end of the latter; but thepresence of the guides b b b on the seatring D prevents any lateralmovement of said valve and keeps it in a true position over the seat oas it moves up and down over the latter, the co-operation of said partsbeing as follows: The guides b extend from the ring D toward the hub d asufficient distance to prevent the valve e, when lifted its maximumdistance above the seat o, from moving laterally, and thereby becomingdisengaged from the spindle. The guides b do not present a sufficientsurface area to materially affect the freedom of the passage through thevalve, and they obviate the necessity,which has here` tofore existed invalve and spindleA connections such as are herein shown, of some deviceor devices attached to either the valve or spindle, or both, whereby theformer is so secured to the latter that it cannot become detachedunintentionally.

In the constructionherein shown the valve e is put upon the end of thespindle or taken off from the latter while the hub and spindle ICO aredetached from the body A, and the moveupwardly-extending guides b b, thefiat-faced 1o ments of the Valve to and from the seat 'u' are valve e,of diameter t0 fit between and bear always Within the space inelosed bythe guides against guides b, and the operating-spindle by. bandin thedirection ofthe length of thelatter. which said Valve is moved, allsubstantially 5 What I claim as my invention isas set forth.
